In such case, the contact area between the condensing section of heat pipe and the fin sets is enhanced, thus that the heat-conducting effect is promoted significantly.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a cooler, and in particular, to a cooling device capable of solving the heating problem generated from an electronic element, such as CPU.

2. Description of Prior Art

In order to solve the cooling problem of electronic elements which generates a great amount of heat, such as the CPU of a computer, heat pipe has become an indispensable member associated with current cooling device. Additionally, in order to provide an excellent distribution and cooperation between the fins arranged on the cooling device and the air flow supplied by the fan, it can arrange at least one set of ringed fins to the heat-conducting seat formed in a tube shape as disclosed in the “Cooling Device of Heat Pipe” of Taiwan Patent Publication No. 575154.

The cooling device of heat pipe includes a plate-typed base, a cylindrical heat-conducting tube with two sides opened, a plurality of heat pipes, and a plurality of cooling fins. The heat-conducting tube is integrally laid on the base, while the heat pipe passes through the base horizontally and is combined to the inner wall of the heat-conducting tube with a ring-typed configuration. The radially distributed fins are contacted with the interiors of heat-conducting tube. Meanwhile, a fan can be arranged in the heat-conducting tube, so the fan can fully develop an optimally cooling effect.

However, although there is an excellent distribution and cooperation between the cooling device of heat pipe and the air flow supplied by the fan, it is impossible to develop the heat-transferring effect of individual heat pipe completely, because it ignores the fact that there is too little contacting area between the heat pipe and the fins. On one hand, the cooling device of heat pipe poorly applies the heat-conducting tube as a heat-conducting media between the heat tube and the fins, such that the heat is unable to be transferred to the fins and the heat-transferring effect is influenced. On the other hand, regarding the flat parts of the heat pipe to be thermally contacted with the heat-conducting tube, since there is only one flat face contacted with the heat-conducting tube, while another face is not contacted with any fin or cooling structure, there is insufficient contacting area between the condensing part of heat pipe and the cooling structure. Therefore, the transferred heat can not be dissipated in time, causing the working fluid in the heat pipe unable to be restored to liquid phase, nor a heat exchange can be functioned successfully.

Accordingly, in order to solve aforementioned shortcomings, after a substantially devoted study, in cooperation with the application of relatively academic principles, the inventor has at last proposed the present invention that is designed reasonably to possess the capability to improve the prior arts significantly.

SUMMARY OF THE INVENTION

The invention is mainly to provide a cooling device with ringed fins, in which a heat pipe is applied as a heat-transferring element between a heat-conducting base and at least two fin sets. A condensing section applied as a thermal connection between the heat pipe and the fin sets is shown as a flat shape for the convenience of being positioned between two fin sets. Thereby, the contacting area of the condensing section of the heat pipe and each fin set may be enhanced significantly, and the heat transferring effect may be promoted markedly as well.

Secondly, the invention is to provide a cooling device with ringed fins, including a heat-conducting base, two fin sets, and a heat pipe. The two fin sets are respectively constructed by a metallic stripe that is periodically folded and is arranged as a ring type. The heat pipe has a heated section that is thermally connected to the heat-conducting base, and a condensing section that is extended from the heat-conducting base is further formed as a flat shape, on which two oppositely flat faces are formed. The two flat faces of the condensing section of the heat pipe are respectively contacted closely with the two fin sets by being sandwiched therein. In such case, the cooling device is thereby constructed.

DETAILED DESCRIPTION OF THE INVENTION

In cooperation with attached drawings, the technical contents and detailed description of the present invention are described thereinafter according to a number of preferable embodiments, being not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention.

Please refer to FIG. 1 and FIG. 2, which respectively are a perspective explosive view and a perspective assembled view of the present invention. The invention is to provide a cooling device with ringed fins, which includes a heat-conducting base 1, at least two fin sets 2, and at least one heat pipe 3.

According to a preferable embodiment of the invention, the heat-conducting base 1 is made of materials with excellent heat conductivity, such as aluminum and copper. Its bottom face 10 is contacted closely with an electronic element 4, such as CPU, as shown in FIG. 4. A cooler 12 may be further arranged on a top part 11 of the heat-conducting base 1. The cooler 12 may be manufactured by means of an aluminum extrusion, and has a bottom part 120 closely contacted with the heat-conducting base 1 to be functioned as a heat-transfer connection and a plurality of fins 121 interspaced and integrated on the bottom part 120 to further supply a cooling effect to the heat-conducting base 1.

The fin sets 2 are separately a metallic stripe that is periodically folded and then structured to a ring configuration. The fin sets 2 interspaced one another are upright formed above the heat-conducting base 1 and the cooler 12. After the ring configuration has been made, a hollow part 20 at the centers of the fin sets 2 is formed for providing a circulation of outside air or an installing space of fan (not shown in the figures).

Please refer to FIG. 3 together. In this preferable embodiment, each heat pipe 3 at least has a heated section 30 and a condensing section 31 for making a heat-transferring mechanism existed between the heat-conducting base 1 and the fin sets 2. In this case, the quantity of the heat pipe 3 is plural, and two sides of each heat pipe are respectively configured as a heated section 30 and a condensing section 31. Furthermore, a plurality of lower grooves 110 are arranged on the top part 11 of the heat-conducting base 1, while a plurality of upper grooves 122 are arranged on the bottom part 120 of the cooler 120 corresponding to the plural lower grooves 110. When the cooler 12 is combined to the top part 11 of the heat-conducting base 1, the upper and lower grooves 122, 110 are merged together, whereby the heated section 30 of each heat pipe 3 may be inserted therein, making a heat-transferring mechanism existed between the heat-conducting base 1 and the cooler 12.

Please refer to FIG. 3 and FIG. 4. According to above description, each heat pipe 3 may also be interspaced one another by making each condensing section 31 extended upwardly from corresponding two sides of the heat-conducting base 1. Subsequently, the condensing section 31 of each heat pipe 3 is further formed as a flat shape, on which two opposite flat faces 310 are formed. The two flat faces 310 are respectively contacted closely with two interspaced fin sets 2 by sandwiching corresponding condensing section 31 of the heat pipe 3 therein. Therefore, the contacting surface area of a condensing section 31 with each fin sets 2 is thereby enhanced to further achieve a heat-transferring connection and promote the entire heat-transferring efficiency markedly; namely, the heat-transferring effect of the heat pipe 3 may be fully developed. Additionally, two lid plates 21 shown as ring shape may be respectively added to the outside face of two most external ring sets 2. Each lid plate 21 is made of material with excellent heat conductivity capable of helping the fin sets 2 process cooling procedure.

Again, as shown in FIG. 4, the condensing section 31 of each heat pipe 3 may also be bent according to the ring-shaped arrangement of the fin sets 2. Because of the bending configurations, two condensing sections 31 of any two adjacent heat pipes 3 (initially interspaced) may be further contacted at their ends.

Additionally, as shown in FIG. 5, it is a cross-sectional illustration of another preferable embodiment of the present invention under a using status. In this case, a middle section of the heat pipe 3 is acted as a heated section 30, which directly passes through the heat-conducting base 1, and two side parts of which are extended upwardly from two corresponding sides of the heat-conducting base 1, while another two sides parts are respectively functioned as a condensing section 31.

Furthermore, as shown in FIG. 6, it is a cross-sectional illustration of a further preferable embodiment of the present invention under a using status. In this case, one side part of the heat pipe 3 is still acted as a heated section 30, while another side part is functioned as a condensing section 31. However, the condensing section 31 is only extended upwardly from one side of the heat-conducting base 1 without any interspacing design.

Finally, as shown in FIG. 7, it is a cross-sectional illustration of a further another preferable embodiment of the present invention under a using status. In this case, the middle section of the heat pipe 3 is acted as a condensing section 31 and is correspondingly located above the heat-conducting base 1, from which two side parts of the heat pipe 3 are extended downwardly and respectively penetrate into corresponding two sides of the heat-conducting base 1, in which two heated sections 30 of the heat pipe 3 are interspaced to each other.

According to the aforementioned structure, a cooling device with ringed fins of the present invention is thereby obtained.

Summarizing aforementioned description, the invention is an indispensably novel structure for a compressor indeed, which may positively reach the expected usage objective for solving the drawbacks of the prior arts, and which extremely possesses the innovation and progressiveness to completely fulfill the applying merits of new type patent, according to which the invention is thereby applied.
